Abstract

Acquisition and processing of time-lapse seismic surveys are usually directed toward maximizing the repeatability of the final image. Given the amount of effort devoted to realizing this goal, it is reasonable to ask if we ever reach the point where we have all the repeatability we need. More precisely, does repeatability ever become sufficiently good that further improvement is not worth the additional effort? This article addresses this question using model-based value of information analysis (VOI).
